DYEING APPARATUS.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed May 18, 1908. Serial No. 433,423.

To all whom it may concern:

Be it known that I, JAMES FRIEDRICHS, a citizen of the United States,residing at lVoonsocket, in the countyof Providence and State of RhodeIsland, have invented certain new and useful Improvements in DyeingApparatus, of which the following is a specification.

My invention relates to dyeing apparatus and has for its essentialobjects the thorough and complete application of dye to textile rovings;novel means for mounting the receptacle and its inclosed parts in thevat floor; means for detaching the holder and inclosed parts from theirseat; improved means creating a circulation of the dye liquors throughthe holders; and simplicity, cheapness, and convenience, both inconstruction and operation.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

In the accompanying drawings which form a part of this specification,the drawing is a side elevation partially in central longitudi nalsection of a dyeing apparatus, embodying my invention.

In the drawings, 1 represents the floor and 2 the walls of a dyeing vatmounted upon a suitable base or frame 3. In the end wall of the vat isan opening, 4, in which is the end of a pipe, 5, leading outwardly anddownwardly into a pump, 6, of the usual form, driven from any convenientsource of power through the belt, 7, by the pulley, 8.

9 is the pump eduction pipe, which runs longitudinally of and beneaththe center of the floor of the vat.

10 is a shut off valve in the pump induction pipe.

The floor, 1, of the vat is provided centrally and at intervalsthroughout its length with conical openings, 12, and in each opening isfixed a tapering or frusto-conical inclined plate, 13, provided upon itsupper end with a retaining flange, 14, and upon its lower end, connectedto or integral with a pipe 15, entering the pipe, 9. The plate, 13, isheld in place by screws 13 in the flange, 14. The plate, 13, constitutesa tight seat for the conical lower end portion, 16, of the perforatedspraying tube, 17. The holder or cage base consists of a circular copperplate, 18, provided with a central opening to receive the tube, 17, andanupturned flange, 20, around the opening and bearing against the sideof the tube at a point above the conical portion, 16, thereof. Screws,21, passing through the flange, 20, and entering the wall of the tube,unite the base, 18, and the tube. The base, 18, may be united to thetube in any other convenient manner. Rods, 2-2, upon the base support anannular head, 23. The head and base are connected by reticulatedmaterial which forms the side, 2 of the cage or holder. A removablecover, 25, having a hand hold, 26, is provided to engage the head, 23.The tube, 17, preferably terminates below the plane of the head, 23, andis provided upon its upper end with a ring, 28, adapted to be engaged bya hook, 29, upon the end of a rope, 30, passing over rollers, 31 and 32,mounted in a convenient manner above the vat. In place of an inde'pendent ring, 28, the upper end of the tube, 17, may be flattened andperforated to form an integral ring.

The operation of my structure is as follows: The rovings or othermaterials to be dyed are placed in the cage around the tube, 17, and thecage placed in position in the vat, with tube end, 16, resting tightlyin the plate, 12. The dye liquor is forced by the pump, 6, through thepipes, 10 and 9, thereby propelling the liquor through the perforationsof the tubes, 17, into and through the material around the tube. It isdesirable during the dyeing process to inspect the material beingtreated. Heretofore, this inspection has been difiicult, dangerous, andnever complete, when cages have been used, because of theinaccessibility of the material in the lower portion of the cage and thehigh temperature of the dye liquor. In my apparatus the removal iseasily effected by inserting a hook or other implement in the ring, 28,and pulling vertically thereon, whereby the end, 16, of the tube isforced from its seat, 12, and the cage is elevated any desired height.

The hoisting device shown comprising the rope, 30, and pulleys orrollers, 31 and 32, is convenient but not essential, as any desiredmeans, either mechanical or manual, may be employed. For the purposes ofillustration, only one of the cages is provided with a hoisting device.

What I claim is,

1. In a dyeing apparatus, the combination with a vat, of afrusto-conical inclined plate having a retaining flange secured in anopening in the floor of said vat and terminating in a pipe extendingbelow said floor, a pump eduction pipe connected with said pipe, a cage,a spray tube disposed concentrically therein with its lower end taperedto engage the conical portion of said plate, and means for raising andlowering said cage and spray tube.

In a dyeing apparatus, the combination with a vat, of a frusto-conicalinclined plate having a retaining flange secured in an opening in thefloor of said Vat and terminating in a pipe extending below said floor,a pump eduction pipe connected with said pipe, a cage, a spray tubedisposed concentrically therein with its lower end tapered to engage theconical portion of said plate, and means for raising and lowering saidcage and spray tube, said spray tube being perforated and terminatingwithin the cage.

In a dyeing apparatus, the combination with a vat, of a frusto-conicalinclined plate having a retaining flange secured in an opening in thefloor of said vat and terminating in a pipe extending below saidfloor, apump eduction pipe connected with said' pipe, a cage, a spray tubedisposed concentrically therein with its lower end tapered to engage theconical portion of said plate, and means for raising and lowering saidcage and spray tube, said spray tube being perforated and terminatingwithin the cage, said cage being also perforated.

4:. In a dyeing apparatus, the combination with a vat, of afrustoc0nical inclined plate having a retaining flange secured in anopening in the floor of said vat and terminating in a pipe extendingbelow said floor, a pump eduction pipe connected with said pipe, a cage,a spray tube disposed concentrically therein with its lower end taperedto engage the conical portion of said plate, and means for raising andlowering said cage and spray tube, said spray tube being perforated andterminating within the cage, said cage being also perforated, and thespray tube having means whereby it may be withdrawn and with it thecage.

5. Inca dyeing apparatus, the combination with a vat, of afrusto-conical inclined plate having a retaining flange secured in anopening in the floor of said vat and terminating in a pipe extendingbelow said floor, a pump eduction pipe connected with said pipe, a cage,a spray tube disposed concentrically therein with its lower end taperedto engage the conical portion of said plate, and means for raising andlowering said cage and spray tube, said spray tube being perforated andterminating within the cage, said being also perforated, combined with apump connected with said eduction pipe and a pipe leading from said pumpand connected with the vat near its upper end.

6. In a dyeing apparatus, the combination with a vat having an openingin its bottom and a conical plate extending through said opening andhaving a tube depending through the bottom of the vat for connectionwith a pump, a spray tube frictionally engaged in the conical portion ofsaid plate, a base plate through which the bottom of said tube extends,means securing said base to said tube, an annular head, means connectingsaid base and head, a reticulated material connecting said base and headand forming a cage extending above the top of the spray tube, and aremovable cover to said cage, the spray tube having means whereby it maybe hoisted and with it the cage.

In testimony whereof I have affixed my signature in presence of twowitnesses.

JAMES FRIEDRICHS.
